Installation

General Installation Checks

The checklist below is a summary of the steps required to successfully in- stall a commercial unit. This checklist is intended to acquaint the installing personnel with what is required in the installation process. It does not re- place the detailed instructions called out in the applicable sections of this manual.

1Remove packaging and inspect the unit. Check the unit for shipping damage and material shortage; file a freight claim and notify appropri- ate sales representation.

Note: The 1/2 through 5 ton units have been tied to the skid by (2) shipping bolts. The removal of these bolts will require a 3/8" (9.7

mm)ratchet with a 1/2" (12.7 mm) socket.

The GEV 6 through 25 ton units have been anchored to the skid with (4) angle brackets. Remove these brackets before lifting unit into place.

The GEH 6 through 15 ton units are anchored to the cross brace of the skid with (4) wood screws. Re- move these screws prior to lifting the unit into place.

2Verify the correct model, options and voltage from the unit name- plate.

3Pull out all field attached parts (i.e. filter rack, duct collar, filter and mounting screws) from the unit packaging for field mounting.

4Verify the installation location of the unit will provide the required clearance for proper operation.

5Remove refrigeration access panel and inspect the unit. Be certain the refrigerant tubing has clearance from adjacent parts.

6Fabricate and install duct work.

7Install and connect a condensate drain line and trap to the drain

connection.

WARNING

Hazardous

Voltage!

Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury.

Main Electrical

8Verify the power supply complies with the unit nameplate specifica- tions.

9Inspect all control panel compo- nents; tighten any loose connec- tions.

10Connect properly sized and pro- tected power supply wiring to a field-supplied/installed discon- nect switch and to the main pow- er terminal block 1K1 for 1/2 through 5 ton equipment or 1TB1 for 6 through 25 ton equip- ment in the unit control panel.

11Install proper grounding wires to an earth ground.

Note: All field-installed wiring must comply with NEC and applicable local codes.

Electric Heat Requirements

12Verify that the power supply com- plies with the electric heater specifications on the unit and heater nameplate.

13Inspect the heater junction box and control panel; tighten any loose connections.

14Check electric heat circuits for continuity.

Low Voltage Wiring (AC & DC) Requirements

15Install the zone thermostat, with or without switching subbase.

16Connect properly sized control wiring to the proper termination points between the zone thermo- stat and the unit control panel.

Filter Installation

17Each unit ships with 1" (25.4) or 2" (50.8 mm) filters. The quantity of filters is determined by unit size. The horizontal1/2 through 5 ton units requires a field installation of the 1"/2" filter rack. All sheet- metal bracket, filter and hardware are in a box located on the side of the unit within the unit packaging. All 1/2 through 25 ton verticals and 6 through 15 ton horizontal units ship with the filter rack and filters factory installed.

Note: Do not operate the unit without filters.

GEV, GEH specifications

Trane has long been a leader in the HVAC industry, and their GEH and GEV series of heat pumps are a testament to their commitment to innovation and efficiency. These models are designed to provide substantial energy savings while maintaining exceptional performance, making them ideal choices for both residential and commercial applications.

The Trane GEH and GEV heat pumps feature advanced variable-speed technology, which allows them to adjust their output to match the current heating or cooling demand. This adaptability not only enhances comfort by maintaining a consistent indoor temperature but also leads to significant energy savings by reducing unnecessary energy consumption during partial-load conditions. By running more efficiently at lower speeds, these units reduce wear and tear on components, extending the lifespan of the system.

One of the defining characteristics of the GEH and GEV models is their high SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) ratings. These ratings demonstrate the units' ability to provide efficient heating and cooling throughout the year, contributing to lower energy bills. The use of R-410A refrigerant is another key feature, as it is both environmentally friendly and efficient, ensuring that these systems meet stringent regulatory standards while delivering reliable performance.

Installation flexibility is another highlight of the Trane GEH and GEV series. These units are designed to work seamlessly with existing HVAC systems, making retrofitting straightforward. Their compact design allows for easy placement, even in tight spaces, without compromising performance. Additionally, Trane's commitment to quality is evident in the construction of these heat pumps, as they are built to withstand harsh weather conditions and provide reliable service year after year.

Moreover, both the GEH and GEV models are equipped with integrated smart controls that simplify operation and maintenance. These controls allow homeowners and facility managers to monitor energy usage, adjusting settings remotely and scheduling maintenance checks to maximize efficiency. This technology not only enhances user experience but also promotes energy conservation through intelligent management.

In summary, Trane's GEH and GEV heat pumps stand out for their variable-speed technology, high efficiency ratings, installation flexibility, and smart controls. These features make them an ideal solution for those seeking a reliable, energy-efficient heating and cooling option, reflecting Trane's dedication to performance and sustainability.
